Since entities called place names play an important role in historical big data research, an information infrastructure for collecting, sharing, and utilizing them is necessary. This paper proposes GeoLOD, a toponym information platform. It introduces themes such as creating a geoword dictionary, sharing toponyms in GeoLOD, utilizing GeoLOD API in various applications, and automatically assigning toponym identifiers by GeoNLP. Issues such as interoperability and reusability will be discussed, as well as the current state of research and future challenges.
